Set of conductive elements in contact with the earth. The earth connection is established according to local conditions (type of ground) and the required resistance value (Figure 1). See more Conductor providing the link with the earth electrode. It is generally not insulated, and has a minimum crosssection of 25 mm2 (copper) or 50 mm2 (galvanised steel). See Figure 1 above. See more This is inserted in the earthing conductor. The device is opened in order to measure the earth connection. See more Located at the origin of the installation and/or at the point of entry in each building. It links all the earthing conductors, the main equipotential link and the various protective conductors. See more Electrical link between the earth circuit and the general equipotential link. Can be an integral part of the general equipotential link or the isolating device. See more WebWhen the propeller shaft revolves it is more or less electrically insulated from the rest of the hull. This can result in spark erosion in the shaft bearings and gear. Propeller shaft grounding provides a very low … flylady holiday missions
